SEAL-LOCK.

SPECIFICATION forming part of Letters Patent N 0. 455,686, dated July '7, 1891. Application filed February 28, 1891. Serial No. 383,213. (No model.)

To all whom, it may concern.-

Be it known that we, JAMEs M. HOPKINS and HENRYTESSEYMAN, citizens of the United States, residing at Dayton,- in the county of Montgomery and State of Ohio, have invented certainnew and useful Improvements in Looks for Sliding and other Doors; and we do here by declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in seal-locks, and has for its object the production of a locking device that is especially applicable to sliding doors of freight-oars, though it is equally useful for doors of other construction, as will be hereinafter fully described.

Referring to the accompanying drawings, Figure l is a side elevation of our invention as applied to use, showing the bolt withdrawn. Fig. 2 is a similar view showing the bolt in position when locked and secured by the sealing-wire. Fig. 3 is an end viewof the device ina locked position. Fig.4 is a top edge view showing in dotted lines the stem of the two staples. Fig. 5 illustrates in detail the securing-bolt.

The base-plate A and hasp B are of the usual construction, the former being provided with the end holes a and the central transversely-arranged staple A, while the latter has an eye-hole at one end and the staple-slot at the other adapted to fit over the staple A in the base-plate. The hasp may, if desired, be sufficiently lengthened to provide room for two slots, the outer one being adapted to lock the door when partly open, and thus provide for ventilation.

The essential features of our invention consist in providing and combining with the ordinary hasp and staple an adjustably-seoured locking bolt or pin 0, which consists of the body 0, preferably cylindrical in form, and the slotted head 0', terminating in a suitable handle of, as shown. The width of the slot coincides with the diameter of the bolt D,upon

the projecting end of which it is mounted, so

as to freely slide and swing laterally thereon. A suitable washer d is placed between the head of the bolt D and the outer face of the slotted pin O in order that friction may be reduced. It will be seen that the securingbolt O has both lateral and-vertical movement on the bolt D, and that when said bolt is adjustedin an upright position it will normally drop into the staple A and secure the hasp when the same is in position thereon.

The eyebolt E, which'consists of the body 6, is adapted to pass entirely through the side of the car-door or other object to which it is attached and is there secured by the usual nut, and the shoulder e is so formed as to adjust the entrance of the staple e formed integrally therewith. The free end of the staple thus formed enters only slightly into the structure to which it is secured, while all the strain upon the eyebolt is placed upon the body e. It is not necessary to pierce the wall or door with more than one hole.

In order to adapt the pin to be secured by the sealing-wire, a suitable hole F is formed transversely in the lower end thereof, as shown in Fig. 2.

When the car-door is slid into its closed position, the slotted end of the hasp B is placed over the staple A, the slotted bolt 0 being swung around laterally on the pivot-pin D, as shown in Fig. 1, to remove its cylindrical e'ndfrom the path of the closing-hasp. The slotted boltis then turned into its vertical position and slid down on thepivot-bolt D until its lower end passes through the staple A outside of the hasp, when the sealing-wire is passed through the aperture F in the lower end of the bolt and its ends secured together by a seal, as shown.

In order toenable the door to be seen red by means of an ordinary padlock when desired, the bolt C may be withdrawn and the loop of such lock entered directly in the staple, as will be readily understood.

If preferred,the aperture G may be so placed in the bolt that it will be on the median line of the staple, each stem of which is provided with holes H, and these holes will register with each other, when the sealing-wire may be passed through and secured in the usual manner.

Having thus described our invention, what we claim, and desire to secure by Letters Patent,.is-
